Credit utilisation calculator
Work out how much of your credit limits you're using, card by card and overall, and how much to pay off to reach a lower utilisation. Free, no sign-up, nothing leaves your browser.
Uses the balances and limits you type in; agencies use what your lenders report, usually your statement balance. It doesn't predict a credit score. The starting numbers are only an example.
What credit utilisation is
Credit utilisation is how much of your available credit you are using: your card and credit line balances divided by their limits. A £1,200 balance on a £3,000 limit is 40%. Lenders and credit reference agencies look at it for each card and across all of them together.
Why it matters
Using a large share of your limits can suggest you rely heavily on credit, so a lower utilisation generally looks better to lenders. Paying balances down, or paying before the statement date so a lower balance is reported, both bring it down. Each agency scores differently, so there is no single magic number.
